Abstract: 1,218,861. Grafted maleic anhydride polymers. FARBENFABRIKEN BAYER A.G. 2 Jan., 1968 [2 Jan., 1967], No. 221/68. Heading C3G [Also in Divisions B2 and D2] A graft polymer is prepared from (I) from 95 to 5 parts by weight of a reaction product of a homo- and/or co-polymer of maleic acid anhydride with a primary-tertiary diamine optionally mixed with ammonia and/or at least one primary heterocyclic, aromatic, araliphatic, aliphatic or cycloaliphatic monoamine, which reaction product may be in the form of a salt, as graft substrate, and (II) from 5 to 95 parts by weight of at least one olefinically unsaturated polymerizable comonomer, said primary-tertiary diamine having its primary and tertiary amino groups separated by a linear or branched chain having 2 to 12 carbon atoms, optionally with one or more oxygen or sulphur atoms in the chain, and the substituents on the tertiary amino group, which may be the same or different, being aromatic, araliphatic, or alkyl radicals having 1 to 12 carbon atoms, or the tertiary amino group may form part of a 5- or 6- membered heterocyclic ring optionally containing an oxygen or sulphur atom. Preferred copolymers are those of maleic anhydride with ethylene, propylene, butylene, isobutylene, indene, styrene or a methyl-styrene. Suitable primary-tertiary diamines are dimethylaminopropylamine and dimethylaminoethylamine. The primary monoamine may be e.g. methylamine, t-butylamine, 2-ethylhexylamine, oleylamine, stearylamine, allylamine, ethanolamine, propanolamine, glucamine, cyclopentylamine, cyclohexylamine or hexahydrobenzylamine. Suitable graft monomers (II) include unsaturated acids and derivatives thereof, aromatic vinyl compounds, vinyl esters, ethers and ketones, vinyl and vinylidene halides, olefins and conjugated diolefins. Solutions or dispersions of the graft polymers are used for sizing paper (see Divisions B2 and D2). Examples are given in which (1) n-butyl acrylate and acrylonitrile are grafted on to the acetate of the reaction product of a styrene-maleic anhydride copolymer, 1-dimethylaminopropylamine-3 and cyclohexylamine, the said acetate being present in an aqueous solution, (2) n-butyl acrylate is grafted on to the formate of the reaction product as in (1), the said formate being present in aqueous emulsion, and (3) n-butyl acrylate, acrylonitrile and stearyl methacrylate are grafted on to the acetate of the reaction product of a styrene-maleic anhydride copolymer, dimethylaminopropylamine and monoethanolamine, the said acetate being present in aqueous solution.

Title: Improvements in Casting Machines.
Inventor: STOKES FRANCIS WILLIAM
IPC: B22D13/10
Filed: 1917-01-16
Abstract: 112,057. Stokes, F. W. Jan. 16, 1917. Casting - machines; metal-pouring; moulds. -Relates to centrifugal casting - machines and consists in means for supporting the mould, in means for pouring the metal into the mould, and in means for preventing the casting becoming loose in the mould as it shrinks. Fig. 1 shows a centrifugal machine, partly in section, in which the mould f is made in two parts secured at one end to a faceplate e mounted on a shaft d. The mould is clamped at the other end by a ring g. The metal is introduced through a pourer h having an opening i for the introduction of the molten metal and a skimmer j. The other end of the pourer has a pouring lip l<1> which may also be provided with a skimmer l<2>, and may have a profile to suit the object to be cast. The pourer h is mounted on a stem m which is carried in a bearing n, and is provided with a manipulating wheel h<1>. The inner end of the pourer is supported by a pin o and the outer end on a roller p. A long mould may be supported on a carrier mounted in a movable slide and provided with openings for the introduction of the metal. When the carrier is withdrawn for the removal of the casting, the outer end of the mould and the pourer may be supported by rollers on vertically adjustable supports. To prevent the casting from getting out of centre as it contracts on cooling, the mould may have tapered ends y as shown in Fig. 9. The pourer may be used to introduce silicious cement in a liquid state, which is allowed to set while the mould is rotating to form a lining. Provisional Specification 3005/17 states that tapered notches may take the place of the tapered rings y, shown in Fig. 9.

Filed: 1941-01-22
Abstract: 545,585. Lifting jacks &c. JACKSON, A. Jan. 22, 1941, No. 852. [Class 78 (iii)] A lifting-jack or device comprises a base frame 1 having a raised rear portion 16, Figs. 1 and 3, a lifting member 9 having its rear end pivoted at 3 to the frame, the front end of the lifting member being adapted to raise a load, a link 14 extending between the raised portion 16 of the frame and the lifting member, one end of the link being pivoted and the other end having a sliding connection, and means to move the sliding connection so as to raise the lifting member. The link 14 may be pivoted to the member 9 and be slidably connected to the part 16 of the frame, but in the construction shown in Figs. 1 and 3 the link is pivoted at 15 to the part 16 and carries a cross-bar 12 at its front end resting on the upper surface of the arm 9. Hooks 13 on the cross-bar 12 engage under the top flanges of the arm 9 and keep the bar on the arm. The bar 12 is slid along the arm 9 to raise the latter by means of a pneumatic or other cylinder 20 having extensions 21 pivoted at 22 to the arm 9 and containing a piston 19 with a piston rod 18 fixed to a sleeve 17 on the bar 12. The piston rod is provided with a slot 23 for the pivot shaft 22. In order to prevent the arm 9 from falling down if air leaks out of the cylinder 20, a catch 26, 27 pivoted on the shaft 22 is adapted to engage notches 28 in the piston-rod. The catch is spring-loaded so as to engage the notches 28 in succession, as the piston-rod moves outwards, and may be held out of locking engagement by means of a spring catch 32. Modifications are described in which (1) the fluid-pressure cylinder is pivoted to the raised part 16 of the frame instead of to the arm 9 and its piston-rod is connected either to the end 12 of the link 14 or to an intermediate part of the link ; (2) the link is pivoted at 12 to the arm 9 and its rear end is guided vertically by a slot in the raised part 16 of the frame, this rear end being raised and lowered by a vertical cylinder fixed to the frame ; (3) an electric motor may be used instead of a fluid-pressure cylinder, this motor driving a screw shaft carrying a nut mounted on the end of the link 14 ; and (4) a pneumatic-hydraulic cylinder 76, Fig. 18, may be used carrying a closed hollow piston 77 having a cup leather 78 forming an hydraulic seal in the cylinder. A pipe 79 connects the closed end of the cylinder to the piston interior. Liquid fills the rear end of the cylinder and also the lower part of the piston. Compressed air is admitted by a pipe 81 to the interior of the piston and forces liquid into the cylinder so as to move the piston outwards.
